In the support frame 30 that the second top cover 7 is connected, the other end of the second support plate 32 is connected with an anti-collision structure 40 through a shaft connection mode, the anti-collision structures 40 are respectively arranged on two sides of the first cavity 3 covered by the second top cover 7, and after the second top cover 7 is turned up and the clamping opening 36 clamps the limiting block 33, the support frame 30 is provided with a supporting force through the anti-collision structures 40, so that the position of the support frame 30 is kept unchanged.

As a further preferred embodiment of the foregoing embodiment, as shown in fig. 12, the anti-collision structure 40 includes a top plate 41, a first connecting plate 42 and a second connecting plate 43, where the top plate 41 is located outside the end portion near the side where the first top cover 6 is connected to the lamp housing 2 by a shaft, and abuts against the end portion of the first top cover 6 when the first top cover 6 rotates, a second mating hole 44 is provided in the middle portion of the top plate 41, a second spring 45 is penetratingly mated in the second mating hole 44, a positioning screw 46 with a threaded end led into the wall surface of the lamp housing 2 is mated in the middle portion of the second spring 45, a nut cap of the positioning screw 46 is pressed against the end surface of the second spring 45, the first connecting plate 42 is fixedly connected to the end portion of the top plate 41 far from the side of the first top cover 6, one end of the second connecting plate 43 is provided with a second sliding groove 47, the other end of the first connecting plate 42 is mated with a second connecting shaft 48 with a limiting end, the other end of the second connecting plate 43 is mated with the second sliding groove 47, and the other end of the second connecting plate 43 is connected to the other end of the second supporting plate 32 by a shaft, which is close to the limiting end of the first connecting plate 42 and the wall surface of the second connecting plate 43 is close to the upper end of the first connecting plate 43.

After the second top cover 7 is turned up, since the second connecting plate 43 is used as an object for providing a supporting effect for the support frame 30 connected to the second top cover 7, the position of the second connecting plate 43 moves towards the first top cover 6, the second connecting shaft 48 pushes against the end of the second chute 47 close to the support frame 30, so that the acting force is transferred to the first connecting plate 42, the acting force is transferred to the second spring 45 by the first connecting plate 42, the acting force compressed by the second spring 45 reversely supports the second connecting plate 43, so as to provide a supporting force for the support frame 30 connected to the second top cover 7, and the end of the first top cover 6 connected to the lamp housing 2 by the axle abuts against the baffle, so that the anti-collision structure 40 can provide a sufficient supporting force for the support frame 30.

Secondly, if the second top cover 7 is covered onto the lamp housing 2 in the direction of the first top cover 6 under the action of external force after being turned up, there is a possibility that the photosensitive controller 8 collides with the lamp housing, and because both the first supporting plate 31 and the second supporting plate 32 are on a straight line and cannot rotate with the first connecting shaft 35 as a rotation axis, when the second top cover 7 swings in the direction of the first top cover 6 under the action of external force, the supporting frame 30 takes the shaft connecting end of the second top cover 7 and the second connecting plate 43 as a point for transmitting the acting force to the second connecting plate 43, and after the compression amount of the second spring 45 reaches the maximum value, the position of the second connecting shaft 48 is not changed again, and the limiting plate 49 limits the situation that the shaft connecting side top cover of both the first connecting plate 42 and the second connecting plate 43 rotates, so that the second connecting shaft 48 can prop against the end of the second sliding groove 47 far away from the first top cover 6 side, and the second top cover 7 receives the acting force to offset the second top cover 7 through the compression of the second spring 45 and the inner wall of the lamp housing 2, so that the second top cover 7 is prevented from colliding with the photosensitive controller 8.

In addition, when the second top cover 7 is covered on the lamp housing 2, by pulling the second top cover 7 in a direction away from the first top cover 6 side, the support frame 30 and the first connecting plate 42 can move in a direction away from the first top cover 6 side during the pulling of the second top cover 7 until the stopper 33 can be removed from the clamping opening 36, and then the first support plate 31 and the second support plate 32 can swing and fold.
